Arduino+0.96OLED+GY30光照传感器Module UNO
一、电路连接
VCC <-----> 5V
GND <-----> GND
SCL <-----> A5
SDA <-----> A4
ADD <-----> NC
OLED接线方式：
VCC<————>3.3V
GND<————>GND
SCL<————>SCL
SDA<————>SDA
LED1<————>10
LED2<————>11
二、实验材料
Uno R3开发板
GY-30光照传感器
面包板及配套连接线
2个LED灯
1个0.96OLED
三、功能
1、OLED实时显示光照强度
2、当光照强度大于600LX时关灯
3、当光照强度大于200小于600时打开冷光灯，并随着光强度变化而变化，强度越大灯光越暗（PWM调节），同时OLED显示开关状态；
4、当光照强度小于200时打开暧光灯关闭冷光，并随着光强度变化而变化，强度越大灯光越暗（PWM调节），同时OLED显示开关状态；
5、使用u8glib库操作OLED屏
6、串口实时发送相应标志数据，可通过ESP8266发送到APP端显示参数
特点：无需人为干预的自动控制设备。
